LENS PROCESSING CONTROLLER, LENS PROCESSING CONTROL PROGRAM, LENS SHAPE DETERMINATION METHOD, AND SPECTACLE LENS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To accurately and efficiently perform a series of processes from shape measurement to quality determination if the quality determination is made after making the shape measurement of a spectacle lens having been subjected to V-block processing.SOLUTION: A lens processing controller comprises: predicted shape identifying means 201b for identifying a predicted finished shape of a V-block cross-section in view of a processing tool interference amount when V-block processing is performed on an unprocessed spectacle lens; contact form identifying means for identifying a contact form of a probe of a lens shape measuring instrument 251 with V-block of the spectacle lens having the predicted finished shape; theoretical shape identifying means 201d for identifying a shape measuring result possibly obtained by the lens shape measuring instrument 251 if the contact form reflects the shape as a theoretical shape of a spectacle lens edge; and shape comparing means 250c for comparing an actual shape obtained actually by the lens shape measuring instrument 251 with the theoretical shape for the spectacle lens edge after the V-block processing, and for determining whether the actual shape is good on the basis of a comparison result.
